PACKING ATTACHMENT FOR COTTON-PRESSES.

SPECIFICATION forming part of Letters Patent No. 327,858, dated October6, 1885.

Application filed July 25, 1885.

To all whom it may concern.-

Be it known that 1, JOHN B. BRADFORD, a citizen of the United States,residing at San Marcos, in the county of Hays and State of Texas, haveinvented certain new and useful Improvements in Packing Attachments forCotton-Presses, of which the following is a specification.

This invention relates to an improvement in re packing attachments forcotton-presses; and it consists in certain peculiarities of theconstruction and arrangement of the same, substantially as will behereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I Will now proceed to describe itsconstruction and operation, referring to the accompanying drawings, inwhich- Figure 1 is a perspective View of my invention; Fig. 2, a sideelevation of the same, and Fig. 3 a top plan View.

A represents the top of the pressure-chamber of a cotton-press, of anydesired construc- 2 5 tion, not necessary to illustrate or describe inthis connection. From this press rises a frame, B, provided with asuitable guide, B, in which slides a standard, B having upon its lowerend a plunger, 13 for pressing the material into the press. The slidingstandard B has upon one side a series of rack-teeth, b, by which thepacker is advanced and retracted, as will be presently described.

J ournaled in suitable boxes on the frame B 3 5 is a transverse shaft, Bcarrying a pinion, b,

which meshes with the rack upon the standard to impart motion thereto,as fully seen in Fig. 1. This shaft extends out at one side of theframe, and has upon its end a pinion, b

0 by which it is revolved,either forward or back, as may be desired, toraise or lower the stand ard and its packing-plunger.

On one side of the main frame, in suitable supports, 0 G, is ahorizontally-sliding frame,

O, which is moved by means of a hand-lever, C fulcrumed on the side ofthe frame, and provided with a sector-rack, C by which the lever and itssliding frame is held at any desiredpoint. This frame 0 is upon eachside Serial No. 172,615. (No model.)

of the shaft B provided with a short shaft, 0, each of which is providedon its outerend with a gear, D, which mesh, and one receives motion fromthe other. Each shaft is also provided with a pinion, d, and one of themalso has a belt-pulley, d, to which power is applied by a driving-beltfrom any suitable motor. It will be observed that the shafts 0 and theirpinions are placed at such a distance that only one of them will engagethe pinion b at the same time, and one or the other is brought intoengagement as the frame is shifted.

In operation the cotton is placed in the chamber A, and by shifting theframe 0 one of the pinions dis brought into engagement with the shaft Band the packinghead driven down to compress the material into thepressboX. The shifting of the frame 0 engages the other pinion, d, andlifts the plunger again, and this is repeated till the press hasreceived sufficient to form a bale,which is then pressed and bound inthe usual manner. When not in use, the plunger is drawn up to 1tshlghest point, and held there by means of a lockinglever, D, the frame 0being then shifted, so that neither of the pinions d will engage theoperating-shaft. This enables the belt-pulley to be run at all timeswithout stopping, whether the attachment is in use or not.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a packing attachment for cotton or other presses, a main frameprovided with guides, a cogged standard sliding therein and carrying thepacking-piston, and an operating shaft carrying a pinion engaging thestandard, and a driving-pinion on its end, in combination with twoshifting driving-shafts, each provided with a pinion, which are engagedwith the operatingshaft alternately to raise and lower the plunger,substantially as and for the purpose set forth.

2. In a packing attachment for cotton or other presses, the combination,with the operating-shaft stationary on the main frame, of a sliding sashor frame, a pair of drivingshafts journaled thereon and geared together,

and carrying driving-pinions, and a lever fuland the shifting-lever Gand its sector-rack IO crumed on the main frame for shifting the 0 allconstructed and arranged to operate sliding frame and its shafts,substantially as substantially as and for the purpose set forth.

and for the purpose set forth. In testimony whereof I affix my signaturein 5 3. The frame 13, guide B, standard B'flhavpresence of twowitnesses.
